Question

6. (1 pt) On the diagram of a p-n junction shown below, indicate the voltage polarity,+ or - needed to turn the switch on permitting current to flow across the junction. 7. (2 pt) Which one of the following substances will have hydrogen bonding as one of its intermolecular forces? A) 0 0 HOHHH 1- C C - N Ć-H H-C-H H2C- C- CF, 8. (2 pt) The monomer T polymerizes via addition polymerization to form a syndiotactic polymer. On the polymeric backbone shown below, complete the syndiotactic polymer by drawing in the substituent groups: Note that one functional group has been added for guidance; include all additional groups needed.

Answer 1

6 The Patyre semiconductor of Pan junction must be connected to positive terminal of battery Whereas the on-type semiconductor u connected to the negative terminal of the battery to allow the corrent to flow acrom the junction, holes CPolitive change) move towards the on-type semiconductor while the electrons (negative charge) move towarde podype semiconductor.

074 HO 7) Hydrogen bonding is possible with hydrogen atome bonded to Noforo. Among the given molecules only 6 has it's bonded to No Therefore only ① has H-bonding hi h Hydrogen wat banding Sindio tactic polymer hat same configuration at the alternating chiral center in the polymer backbone. lele
